OT Animal Variations: Sheep vs. Rats • An ewe is able to recognize her own lamb from the moment it is born, and she feeds it alone. • This involves an ‘olfactory memory’ of the lamb that is fixed by neural pathways activated at parturition by centrally released oxytocin • Virgin and early pregnant rats typically avoid contact with newborn pups, but at the end of pregnancy, when the neural circuits regulating maternal behavior are established, rats lose this apprehension.
Sheep vs. Rats (cont.) • 'Motherhood' changes the neuroendocrine response o Now oxytocin will release into the blood and hypothalamus following emotional, physical, or pharmacological stressors that are attenuated in the peripartum period
